Step 3 - Connect Communication and Power Modules
Firmware upgrades also include firmware that operates the Communication and Power
Modules. If these modules are part of your system, attach them to the GPS Receiver
Module prior to uploading the firmware to ensure that all modules are at the same level
of firmware. To do so, power off the unit then attach the modules to it, insert the SD card
in the receiver with it still powered off, then proceed to the next step.
If for some reason these modules are unavailable at this time, the new firmware can be
loaded to the receiver now and reloaded a second time once the modules become
available.
Step 4 - Initiate Firmware Upload
With the receiver powered off, initiate the firmware upgrade process by pushing the UP
arrow key and the Power button at the same time. The unit will beep after about 3
seconds, release the key and wait. The receiver will check the SD card to ensure that
the firmware file is on the card and that the file is not corrupted. If a good file is found on
the SD card, the receiver will start the upgrade. Go to Step 5.
If the firmware file is not found on the SD card, the front panel display will show the
message "No firmware to upgrade" and all 4 indicator LEDs will blink red. Power cycle
the receiver to clear this state, and then insert an SD card with valid firmware.
If the firmware file is corrupted, the front panel display will show the message "Bad
image checksum, will not upgrade" and all 4 indicator LEDs will blink red. Power
cycle the receiver to clear this state, and then acquire another copy of the firmware from
Technical Support.
Step 5 - Monitor the Upgrade
The firmware upgrade is executed in five stages, and each stage will show a message
on the front panel display. As the upgrade proceeds, you should see the following
messages:
• "Loading Thales firmware stage #1"
• "Loading Thales firmware stage #2"
• "Loading Thales firmware stage #3"
• "Loading Thales firmware stage #4"
• "Loading Thales firmware stage #5"
If the Power Module is not connected to the GPS Receiver Module, Step 1 is skipped
and the message "No answer from the BATT Module stage #1 skipped" is displayed.
If a Communication Module is not attached, Step 2 is skipped and the message "No
answer from comm module stage #2 skipped" is displayed.
